Cyberslut

Sean was excited to be home. His unit was not supposed to return from Iraq for another week, but just a day earlier they were told to board a plane and leave. He had not contacted anyone at home, mostly because he did not have time, but he also wanted to surprise them. He was especially excited about seeing his younger sister Amanda who had just turned 18 and was going to graduate from high school in a few months.

The taxi pulled in front of their modest house. It was still winter and there were traces of snow and ice covering the front yard. Sean walked to the front door and turned the knob. The door was open. He quietly stepped inside, but no one was there. When he called out no one answered so he headed back towards his room to unpack and wait. That's when he heard noises coming from his sister's bedroom.

Sean stopped and peeked through the door which was cracked open. Amanda was sitting in front of a computer and typing with one hand. The other hand was between her legs. Her jeans and panties were on the floor by the chair and her knees were spread wide. Sean could hear moans between the clicks of the keys.

Sean was shocked. His sister, who had been an innocent young teenager when he joined the Marines, was engaged in a hot session of computer sex. He knew it was wrong to watch but he couldn't seem to break away. He could feel his cock growing hard as he watched his sister getting more and more excited. Her fingers caused faint squishing sounds to emanate from her pussy.

Amanda was becoming more and more excited as she clicked away on the computer. Suddenly her knees began to wobble. She arched her back and straightened her legs. Her toes curled and her body jerked in a series of spasms. She let out a muffled squeal and a series of gasps and moans. Several seconds later her body collapsed back into the chair until her trembles subsided and she regained control.

Amanda, now with both hands free, continued typing for another few minutes. Then she stood and bent over to pick up her jeans and panties. Sean stared at her naked ass with two perfect spheres separated by a cleft down the middle. Between them he could see her swollen pussy with the petals open wide and glistening with cum.

Sean made a quick escape while Amanda pulled on her clothes. He went back outside with his bag, gave Amanda a little time to recover and then re-entered making his presence known in a loud voice. Amanda came running out from the back room and flung her arms around him in a big hug. He was very aware of her breasts pressing into his chest and hoped she did not notice his still hard cock.

"Sean, I can't believe it. You're home. I have missed you so much. I'm calling mom and dad right now. They will be so totally freaked."

The celebration went on well into the night with neighbors and friends dropping by until Sean could hardly stand because of the jet lag. The next morning he woke late. He found a note from his parents saying they were all out shopping and would be back by noon. Sean contemplated getting something to eat, but when he passed Amanda's room he opened the door and stepped inside.

Her bed was not made and there were clothes strewn about, including a pair of panties on the floor. He picked them up and sniffed the crotch. There was a strong smell of pussy. Sean assumed that these must be the panties his sister was wearing after masturbating at the computer the previous afternoon.

Her computer was on. Out of curiosity Sean moved the mouse to clear the screen saver. He was surprised to find someone still logged on to a porn chat site by the name of "Puffy n Wet." He knew it had to be Amanda. Sean scrolled up and read the first entry from someone named "Meat Grinder." It was from last night.

MG: I quietly move up behind you in the dark alley.

PW: I sense someone is there. I am afraid. I turn to look.

MG: My hand clamps across your mouth. I twist your arm and push you face first against the brick wall.

PW: I try to scream but am unable. I struggle to get free.

MG: I twist your arm higher.

PW: The pain is unbearable. Tears run down my cheeks.

MG: Cooperate and you won't get hurt.

PW: I nod my head.

MG: I take my hand from your mouth and slide it down to your breast. I crush the soft flesh through the flimsy top you are wearing. My other hand slides around your body and cups your pussy.

Sean wrapped her panties around his cock and closed his eyes. He imagined Amanda's lips wrapped around his hard meat as she looked up at him. Seconds later a huge load of cum gushed into the crotch. He kept shooting until her panties were drenched. Afterwards he felt guilty. A brother wasn't supposed to think of his sister like that.

Sean wondered if "Meat Grinder" was her boyfriend and if they just used the internet when they couldn't be together. He decided to test the waters and set up an account using the name "Marine One." He noticed that there were a lot of options including video, and that there was also a search and messaging feature.

Sean composed a message to Amanda that he was sure would get her attention and hit the send key. Sure enough he found a reply later that afternoon from "Puffy n Wet" who asked him to meet her in a public chat room at 10PM that evening. From there she suggested that they could go into a private session.

Sean said goodnight to Amanda at a few minutes before 10PM and watched her go into her room and lock the door. He did the same and set up his laptop next to the bed. He logged onto the site and went to the chat room where "Puffy n Wet" sent him a message inviting him to a private chat. Sean accepted.

MO: I'm new at this. How do we get started?

PW: There's nothing to it. We just make it up as we go along.

MO: Are we supposed to be using video so we can see each other?

PW: No. I don't do video or voice. We just type what we want to do.

MO: So how does that work. Do I ask you to take off your clothes or something?

PW: I'm already naked except for a pair of panties. And you?

MO: The essential organ is fully exposed and ready for action.

PW: You mean your cock? Is it hard?

MO: Not yet.

PW: I can help with that. Do you want me to suck it?

MO: Sure, but how does that work? I need an image in my mind.

PW: I can be anyone you want - a movie star, a girlfriend, a wife, a mistress.

MO: How about my sister? Could you be her?

PW: Wow, that's a little kinky. Do you really have the hots for your own sister?

MO: Yeah, after I saw her naked. She didn't know I was looking.

PW: Was she in the shower?

MO: No, she was masturbating in her bedroom. She left her door open.

PW: That is hot. What did you do?

MO: I jerked off in a pair of her panties.

PW: You are kinky. Ok, I'll be your sister.

MO: And I'll be your brother. Do you have one?

PW: Yeah. I never really thought about sex with him but he is pretty hot.

PW: I don't know. Maybe. I liked the idea of sucking his cock just now.

MO: Well I'd definitely fuck my sister if I got the chance.

PW: Then go for it. I gotta go pee. Talk to you soon.

MO: OK. Goodnight.

Sean heard Amanda's door open. She walked down the hallway to the bathroom. He waited until he heard the toilet flush and stepped into the hallway wearing only his briefs. He slowly walked towards the bathroom. Amanda stepped out wearing an oversized t-shirt that fell just below her pussy. Her hard nipples poked out through the thin material. They stood and stared at each other. Sean broke the silence.

"Um... Hi Amanda. I was just on my way to the bathroom."

Her eyes took in his muscular body and then glanced briefly at the bulge in his briefs before looking away.

"Oh. Okay. It's free now."

Sean knew it would be up to him to make the first move. He knew now that she found him sexually attractive and was not repulsed at the thought of sucking his cock. He took a step closer. He glanced down at her tits and then up into her big brown eyes.

"Did I ever tell you how sexy you are, Amanda? You must drive the boys at school crazy. That probably sounds a little weird coming from your brother, doesn't it?"

She shrugged her shoulders and looked down at the ground.

"Not really. I mean you're a good looking guy too. If you weren't my brother I'd be attracted to you."

Sean put his hand under her chin and lifted her head until their eyes met.

He leaned his face into hers and brushed against her lips. He pulled back to see her reaction. Her eyes were filled with desire.

"I want to kiss you Amanda. A kiss isn't wrong, is it?"

He leaned forward again and kissed her. Amanda was frozen and unsure what to do. His lips parted. Amanda felt his tongue and opened her mouth. Sean pulled her closer until he could feel the warmth of her body against his. She wrapped an arm around his neck. Sean pulled away from the kiss and touched her cheek. Their faces were inches apart.

"Stop me if you think this is wrong, Amanda."

Their lips met again, this time with more urgency. Sean slid his free hand under her t-shirt and cupped his sister's naked breast in his palm, gently squeezing it with his fingers. Amanda moaned and straddled her brother's thigh. Sean could feel the curls of her pubic hair against his skin. His other hand slid down her back, under the t-shirt and over the rounded cheek of her firm ass. His fingers gently massaged the creamy skin.

They continued to kiss shamelessly in the hallway afraid that if they stopped the spell would be broken. Sean pinched her swollen nipple. Amanda rubbed her pussy against his thigh. She could feel his hardness pressing against her lower stomach. Sean bent his legs and shifted his bulging cock so that it was pressed against his sister's pussy. She pushed back against him.

Sean took his hand from Amanda's breast and cupped the other cheek. He pulled her tighter against his cock. Amanda spread her legs and fucked her pussy up and down his length. Using both hands, Sean lifted his sister into the air and pressed her back against the wall. She wrapped her arms around his neck and dug her heels into his buttocks.

Amanda moaned when Sean sunk his teeth into her neck. She rubbed her clit against the tip of his cock which was poking up through the elastic in his briefs. She could no longer hold back the pressure boiling in her loins. Her fingernails dug into his shoulder. She threw her head back and squealed. The explosion that ripped through her pussy rocked her body. She thrashed and bucked in a series of convulsions.

Sean lowered his sister's trembling body until she was standing on wobbly legs. Their lips pressed together and their tongues mingled in a hot passionate kiss. Amanda slipped her hand between them and slid it down into Sean's briefs. Her fingers curled around his hard flesh and slowly pumped it up and down.

She moved her lips down to his neck and nibbled on the tender skin. She slid down the wall until she could suck his nipple into her mouth. Amanda continued down his body trailing her tongue over his stomach. She hooked her thumbs into the elastic of his briefs and peeled them down his thighs. Sean's hard cock wavered in front of her face. Amanda stared at the vein streaked flesh before darting her tongue over the swollen knob.
